Return a pointer to a specific ghost in a trees struct plus pointers to its face_neighbor and tree_to_face arrays.

Parameters:

trees – [in] The trees structure where the ghost is to be looked up.
lghost_id – [in] The local id of the ghost.
face_neigh – [out] If not NULL a pointer to the ghosts face_neighbor array is stored here on return.
ttf – [out] If not NULL a pointer to the ghosts tree_to_face array is stored here on return.

Returns:

A pointer to the tree with local id tree.
